The Stone Maze is an area that is accessible from the hammer in Blood World.
Features
The maze is made of gray stone or concrete with a scrolling background of a blood splatter. You can fly above some of the broken paths using the Fairy or Space Suit effect.
There are a lot of Scary Faces in this area that will send you to an isolated area if you are caught. You can evade them using the Bug effect.
To get to the Bowling Zone, travel south and continue until you see a red bowling ball (this is the portal).
Kanashii-Tan can be found by going in the following directions at the first-encountered intersections (starting from the intersection right before the portal to the Bowling Zone): east, south, east. There should be a small, tunneled entrance; Kanashii-Tan is inside this room.
If you take a left at the intersection right before the Bowling Zone portal, then go north at the second intersection after that and continue north, you'll encounter a portal to the Spelling Room.
There's a sectioned off area with four humanoids with an eye for head. Using the Eyeball Bomb effect will make them run in your direction and stare at you.
Using the door in Seishounen's apartment will teleport you to a sectioned off area in this map. In this small segment there's also a portal to the Magnet Room.
